§85.1903 - Emissions Defect Information Report 

(c)(1) The manufacturers corporate name. 

Jaguar Cars Limited. 

(c)(2) A description of the defect. 

Drivers of Jaguar XK vehicles report M.I.L. illumination, broken fuel filler cap tether / magnetic re-fuelling 

stowage feature, or a broken fuel filler cap. 

Dealers replace fuel filler caps as a matter of course during investigations, resulting in an artificially high number 

of reported claims. 

A broken fuel filler cap tether or magnetic re-fuelling stowage feature has no affect on sealing performance. 

When a fuel filler cap handle breaks the sealing mechanism is unaffected. 

(c)(3) A description of each class or category of vehicles potentially affected by the defect including make, 

model, model year, and such other information as may be required to identify these vehicles. 

See table in section (c)(4)(i) below. 

(c)(4) For each class or category of vehicle or engine described in response to paragraph (c)(3) of this section, 

the following shall also be provided: 

(c)(4)(i) The number of vehicles or engines known or estimated to have the defect and an explanation of the 

means by which this number was determined.

(c)(5) An evaluation of the emissions impact of the defect and a description of any driveability problems which a 

defective vehicle might exhibit. 

Defective fuel filler caps as described in this report may increase evaporative emissions as owners may be 

unable to properly fit or torque a broken cap. 

There is no adverse impact on driveability associated with this component. 

Defective fuel filler caps as described in this report may illuminate the MIL if not properly fitted or torqued.

(c)(6) Available emissions data which relate to the defect. 

There is no data available quantifying the impact on emissions of this defect. 

(c)(7) An indication of any anticipated manufacturer follow-up. 

Current process of addressing defective caps through warranty replacement is considered satisfactory for the 

defect type and rates observed. However, Jaguar will continue to monitor claims and re-evaluate action plans 

periodically.
